Title: Electronic time indicating hands position memory - retains number of forwarding steps if working voltage drops or fails in radio-controlled clock
Inventor: ALLGEIER ULRICH DIPL ING
IPC: G04G7/00
Filed: 1990-03-20
Abstract: A number corresp. to the indicating hands' position is stored in a volatile electronic data memory (5) for each step of the hands (2). When a working voltage monitor (7) identifies a drop in the working voltage or its interruption. This indicating number is stored in a non-volatile memory (6). Upon increase in the working voltage or its application the number is read out from the latter (6) and compared with the hand and/or calendar position given by the radio time signal decoder (85). The number of steps required is calculated by an electronic computer (4) and applied to the positioning motors (1) driving the clock hands and/or calendar display. ADVANTAGE - Allows automatic positioning of hands to received time signals upon application of working voltage, e.g. from battery without having to note hand position and independently of size of mechanical components.

Inventor: FRIEDRICHSEN WELM
IPC: F15B11/16
Filed: 1991-08-19
Abstract: In a hydraulic system with a pump (1) and load (4, 104), a bleed valve (16) is provided, which is connected to the pump pressure side (3) and opens towards the tank (2) when a predetermined pressure difference between the pump pressure and maximum load pressure is exceeded. This bleed valve is used in addition to a pump control device (22), wherein provision is made for the pressure difference at the bleed valve (16) to be somewhat greater than the pressure difference preset at the pump control device (22). The control apparatus (20) can preset the pump delivery rate in dependence on setting signals (s1, s2) and regulate it in dependence on a difference pressure signal (U). In addition, it is possible to compare the pressure difference signal with a pressure difference limit and to throttle the control valves (6, 106) in dependence thereon, in order to prevent overloading. The transducer delivering the pressure difference signal can be a position sensor (18) at the bleed valve (16). As a result, the performance of the hydraulic system can be improved in a simple manner.
